alt Hacker News> We could probably slash gas prices by banning oil exports, thus removing domestic oil supply from global market pricing (barring smuggling).
To my understanding, you couldn't do this, no. The US is a net oil exporter, but many of its refineries are tuned for processing oil with a chemical composition that isn't found in the US, or not found in sufficient quantity. So the US has to both import and export oil, it can't just replace imports with exports.

How difficult would it be to retune those refineries to process domestic oil instead? In a world where a heavy-handed extreme like “banning oil exports” is on the table, surely doubling down on the heavy-handedness wouldn't be out of the question.
